CL31C472JEH1PNE 产品概述
一、产品简介
CL31C472JEH1PNE 是三星（SAMSUNG）生产的多层陶瓷电容（MLCC），规格为 4.7nF（472），容差 ±5%（J），额定电压 250V，介质类型 C0G（又称 NP0），封装 1206（英制）/3216（公制）。该系列以介质稳定、损耗低、温度特性优良著称，适用于对容量稳定性和低噪声有较高要求的电路。
二、主要特性
- 容值：4.7nF，公差 ±5%；适合精密滤波、振荡、定时等场合。
- 介质：C0G/NP0，温度系数接近零，随温度变化的容量漂移极小，线性好。
- 额定电压：250V，适用于中低电压电源耦合、隔离及高压滤波场景。
- 封装：1206，适中体积，便于自动贴片，兼顾体积与电气性能。
- 低损耗、低等效串联电阻（ESR）和稳定的绝缘阻抗，可靠性高。
- 符合无铅（RoHS）工艺要求，适合常见无铅回流焊工艺。
三、典型应用
- 高频振荡器与时钟电路的耦合/定时元件。
- 精密滤波与阻尼网络，需要容量随温度和电压保持稳定的模拟前端电路。
- 开关电源与电机驱动中作为高压侧的旁路/抑制器件（取决于电路要求）。
- 通信设备、测量仪表、传感器和射频前端（对射频性能有要求时需结合电路仿真验证）。
四、使用与注意事项
- 虽然 C0G 的直流偏压效应远小于高介电常数材料，但在接近额定电压下仍可能出现轻微电容下降，设计时建议留有裕量。
- 封装为 1206，贴片时注意基板和焊膏的布线与焊盘设计，避免热应力和机械弯折导致裂纹。
- 推荐采用常规无铅回流焊曲线焊接，避免手工过热焊接。
- 储存环境应避免潮湿、高温和机械冲击，开封后尽快使用以减少污染风险。
五、可靠性与采购信息
CL31C472JEH1PNE 属于三星成熟的 MLCC 产品系列，经过批量验证，具有良好的抗潮湿、抗热循环与机械冲击能力。常见包装为卷带（tape & reel），便于 SMT 贴装。选型时可参考供应商样片或完整数据手册以获取详细的温度范围、绝缘阻抗、寿命与焊接曲线等参数。
六、小结
总的来说，CL31C472JEH1PNE 是一款适用于精密模拟与高稳定性场合的 4.7nF C0G MLCC，兼具中等电压等级与良好热稳定性。若电路对容量稳定性、相位噪声或温漂有严格要求，该型号为可靠且易于量产的优选。采购与设计前建议参考三星完整规格书并结合电路实际工况做电气与热仿真验证。

Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Sourcing availability signal
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
Examples of how common component sourcing requests are organized.
Typical RFQ scenarios based on the WMSIC form fields, catalog data, manual review steps, and shipment preparation workflow.
The buyer shares the full part number, package requirement, quantity, destination, and available product photos so the quotation can record the exact version under review.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
